TYPE-WRITING. MACHINE.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application filed May 14, 1906. Serial No. 316,724.

consists in the features of construction, combinations of devices andarrangements of parts hereinafter fully described and particularlypointed out in the claims. One form of my invention is shown in theaccompanying drawings, wherein F'gure 1 is a vertical front to rearsectional view of a typewriting machine embodying my invention, parts ofthe machine being omitted and parts being broken away. Fig. *2 is a rearelevation of the machine,

parts being omitted and parts being broken away. Fig. 3 vis a full sizedfragmentary top plan view of the ri ht-hand rear part of the machine.Fig. 1 1s a front elevation of the parts shown 1n Fig. 3, the top platebeing shown in section. Fig. 5 is a full sized detached top plan view'ofmyimproved retarding apparatus, the actuating devices therefor beingomitted. Fig. 6 is a vertical sectional view of parts of the retardingapparatus, the view being taken on a plane represented by. the line aa min Fig. 1 and looking in the direction of the arrow at said line.

I have shown my invention as applied to a No. 6 Remington typewriter butit is to be understood that said invention may be adapted to other formsof writing machines. in the drawings, the main frame of the machine isshown, as'comprising a base 1,

corner posts 2 and a top plate 3. Key lovers 4 are fulcrumed at 5 in therear of the base, each key lever being provided with a 'restoring spring6. Connected by a link 7 with each key lever is a type bar 8, said typebar being pivoted at 9 in one of a seriesof liangers 10 secured on thetop plate of the machine. When the key levers are properly actuatedtheir associate type bars coiiperate with the under side of a rotaryplaten 11,

said platen being journaled in a platen frame or carrier 12 having atits frontside a roller 13 cooperative with a shiftable track-way 14. Theplaten carrier is connected by arms 15 and a rock shaft 15 with acarriage truck 16, said carriage truck carrying rollers 17 whichcooperate with a fixed rail or track 18 supported on standards 19 risingfrom the top plate. The platen carrier and carriage truck constitute acarriage or traveling element.

Pivoted to the carriagetruck at 20 are arms 21 curving forwardly anddownwardly over the rail '18 and supporting at their free ends a feedrack 22, sald feed rack normally meshing with a feed pinion 23 which isfixed in a shaft 24 journaled' in a supporting bracket 25 fixed to thetop plate. Loosely mounted on the rear end portion of the shaft 24 andoperatively connected with the pinion 23 is a toothed escapement wheel26 and cooperative with said 2 escapement wheel are escapement dogs 27mounted at the top of the vertically disposed arm 28 of a vibratory dogcarrier or rocker pivoted at 29 in a bracket 30 depending from the topplate, the

dog rocker having a forwardly extending arm 31 to which is fixe'd a yoke32, said yoke having slotted ends with which engage depending hookedarms 33, said arms carry ing at their lower ends a universal bar 34. Theuniversalbar extends from side to side of the machine beneath the keylevers 4 and the spacing levers (not shown) and is adapted to beoperated when the key levers or spacing levers are actuated. Theoperation of the universal bar causes the escapement tabulatorwhieh, asit forms no part of the invention, need be but briefly described, itbeing understood that said invention is equally applicable to otherconstructions of tabulating mechanism. A supporting frame comprising across bar 39 and arms 40 is suitably secured at the rear of the carriagetruck, the arms 40 of said frame having As best seen in Fig. 4, theplate-like suphorizontal and rearwardly projecting extensions to whichare secured by screws 41 a toothed stop bar 42- which receives one ormore column stops 43, said column stops being adjustable longitudinallyof said bar to determine columnar fields, as is well understood. A setof denomination stop members or levers 44 are pivoted at 45 in asupporting frame or bracket 46 which is suitably secured at the rear ofthe machine frame. The upper arms of the levers 44 are provided withforwardly extending stop porvtions 47 which are arranged side by side aletter space distance apart.

The lower ends of the levers 44 are loosely connected to the rear endsof forwardly extending push rods 48, said push rods hearing at the frontof the machine in a detachable bearing bracket 49. .Each push rod isprovided with a key or finger piece'50 and a restoring spring 50 andwhen actuated is adapted to move the stop portion 47 of its associatelever 44 forwardly until said stop portion is in the path of the columnstop or stops 43. In the present instance I have preferred to dispensewith the construction of carriage releasing mechanism commonly employedwith the style of tabulating mechanism now under consideration, and toefiect the release of the carriage, after the cooperative tabulatingstops have been properly positioned, by my retarder itself, saidretarder serving both to effect the release of the carriage and toretard the speed thereof after such release. It is to beunderstood,however, that from certain aspects of my invention it is immaterialwhether the retarder itself effects the release of the carriage aspresently to be described or whether the carriage is released by otherand separate means, such, for example, as the means usually emplo ed inthe style of tabulating. mechanism. il ustrated.

My improved retarding apparatus is preferably guided and supported in abracket which is best shown in Figs. 1, ,2, 4 and 5,

said bracket comprising a depending body portion 51 having at its upperend a rearwardly bent lip 52 formed with openings 53 which receiveheaded screws 54, said screws entering the top plate from the topthereof and serving to secure the bracket fixedly to the frame of themachine. The body portion of the bracket (see especially ing flanges 55,said flanges being formed with oppositely disposed grooved guide ways56, which guide ways cotiperate with laterally disposed lips or flanges57 projecting outwardly from the rear ends of the side portions 58 of aplate-like supporting member 59, said supporting inember being slidableup and down in the guide ways 56 and carrying the retarding devicesproper.

porting member 59 is provided at its left side with an upwardlyprojecting portion 60 which receives a -shouldered screw 61, saidshouldered screw serving as a pivot for a pinion 62, the pinion beingadapted to mesh with the carriage feed rack 22 but being normallyseparated therefrom as shown in Figs. 1 and 2. Constantly meshing withthe pinion 62 is a toothed wheel or rotary device,

63, said wheel being provided with a hub 64 (Fig. 1) which receives ashouldered screw 65, said shouldered screw having a '67 of theshouldered screw 65. The rear end portion of the hub 64 is slightlyreduced and receives a guard member 68. Confined between the front faceof the guard member and the rear face of the'toothed wheel 63 is a sgiral spring 69, said spring, as best shown in ig. 6, having its innerend secured to a pin 70 projecting from the hub of the toothed wheel andits outer end connected to a hooked lug 71 projecting inwardly from oneof the lips 57 of the supporting plate 59. The spring tends constantlyto turn the toothed wheel 63 on the shouldered screw 65 as a pivot inthe direction of the arrow in Fig. 6.

In order to prevent the rotary device or wheel 63 from being turned bythe spring 69 from normal position, I provide stop devices, one of saiddevices comprising a pin 72 fixed at the upper end of a flat spring 73,saidspring, as best shown in Fig. 4, being secured against the frontface of the supporting member 59 by a screw 74. The spring pin 72protrudes rearwardly through an opening in the bodyof the supportingmember 59 and into the path of the other stop member which is in theform of a lug or pin 75 projecting forwardly from thefront face of thewheel .63 near its periphery. The spiral spring 69 tends to maintain thestops 72 and 75 1n engagement, and when sald stops engage, furtherrotary movement of said wheel in the direction of the arrow in Fig. 6 isprevented. If it is desired to increase or decrease theinitial tensionof the spring 69 the stop 72 may be drawn forwardly out of the path ofthe stop 75 by pulling the upper end portion of the spring 73 forwardlyaway from the face of the platelike supporting member 59, and Ithereafter the wheel 63 may be turned one or more turns in eitherdirection as may be desired without interference from .the stop 72.After the tension has beenaltered to the desired extent the end or stop72 is permitism such as that shown and now to be 'de-' whereof, as shownin Fig. 1, is pivoted on an, enlarged portion 67 of the shouldered screw65, said arm 'being confined between the head of the screw and the guardplate 68. The upper arm 76 of the toggle is pivotally connected by apivot pin 77 with the lowerv arm 78 thereof, said lower arm beingpivoted on a shouldered'screw 7 9 secured to the supporting bracket 51as best appears in Figs. 2 and 4. The toggle is adapted to bestraightened and broken by suitable mechanscribed. Pivoted to the pin 77betweenv the arms of the toggle, as shown in Figs. 1, 2 and 4, is a link80, said link being pivotally connected at 81 with the verticallydisposed arm of a bell-crank lever 82 pivoted at 83 to the bracket 51.The shorter horizontally disposed arm of the bell crank projectsinwvardly toward the middle of the machine and is pivotally connected at84 to a link 85, which link in turn is pivoted at 86 to a crank arm 87fixed to the forward end of a rock shaft 88,'sa-id rock shaft beingjournaled in the lower ends of the depending arms 89- of a U-shapedbracket, the cross bar or connecting portion 90 whereof is fixed to theunder side of-the topplate byvheaded screws 91. The rear end portion ofthe rock shaft 88 has fixed to it a short crank arm I 92 projectingoppositely from the crank arm 87. The crank arm 92 is pivotallyconnected at 93 with a vertically disposed link 94, said link beingpivotally connected at 95 with a horizontally disposed arm 96 projectingforwardly from the lower end of the right hand arm (considered from thefront of the machine) of a U-shaped releasing bail. The releasing bailcomprises side arms 97 pivoted at 98 to the opposite. sides of thetabulator bracket 46, said side arms 98 being connected at their upperends by a cross bar orrod 99 which cross bar, as will be understood froman inspection of Figs. 1 and 2, extends from side to side of thedenomination levers 44 near the upper ends thereof and in a position tobe operated by said levers when they are actuated to position theirassociate stop portions 47. p A light coiled restoring spring 100surrounds the rock shaft 88 behind the rearbracket arm, one end of saidspring be ing secured to the bracket arm 89 and the other end to thecrank arm 92. Said spring tends to break the toggle oint in the mannerpresently .to be described.

Referring now to the operation of the retarding apparatus, the movableparts of it 50 is actuated, the upper arm of the associate denominationstop member 44 is swung forwardly about the'pivot 45, said arm in itsmovement actuating the release bar 99, swinging the latter forwardlyabout the pivots 98 and depressing the arm 96, said arm through the link94 turning the rock shaft 88 and the latter through the crank arm 87 andlink 85 operating the bell crank lever 82. The bell cranklever throughthe link tends to straighten the toggle, the arms whereof are normallyat an angle as shown in Fig. 2. The lower arm of the'teggle has a fixedpivot 7 9 so that as the toggle is gradually straightened it serves toslide the supporting member 59 upward in its fixed track ways and tobring the pinion 62 into mesh with the carriage feed rack 22. As theupward movement of the member 59 continues thereafter the carriage feedrack is gradually swung upward about its pivots 20 until it isseparatedfrom the feed pinion 23, thereby releasing the carriage from the controlof the other step-by-step feeding devices. The parts are so proportionedthat when the release of the carriage is effected the projecteddenomination stop portion 47 will be in the proper position tocotiperate with the nearest column stop 43 to the right, so that thecarriage will move in letter space direction under the influence of thecarriage power or spring drum 35 until said carriage is arrested'by thecoiiperation of the projected denomination stop and the columnstop.

When the carriage is released from the step-by-step feeding devices asdescribed, the parts of the retarding device, which it willbe noted hasserved to effect said carriage release, will be in the positionsillustrated in Fig. 4. From an. inspection of this figure it will beunderstood that as the carriage movestoward the'leftafter having beenreleased, the pinion 62 will be turned by the carriage rack 22 in thedirection of the arrow 1) in said figure and the toothed wheel .63 willbe turned by the pinion 62 in the direction of the arrow 0 in saidfigure.

It will be clear, from Whathas been said of the construction of theparts, that the turning of the toothed wheel 63in the direction of thearrow 0 will wind up the s iral spring 69 increasing the tension thereoand consequently increasing the resistance which said spring applies tothe carriage through its connections therewith. It will be apparent thatduring the run of the carriage the resistance applied to it through thespring 69 is a continuously increasing one and furthermore'that saidresistance varies with the distance through which the carriage runs, thegreater the extent of the run the greater being the resistance. Theresult is that, as the momentum of the carriage increases, theresistance applied thereto by the retarding devices also increases. Itis, of course, to be understood that the pulling force exerted by thecarriage power or spring drum 44 is greater than the pulling forceexerted by the spring 69 of the retarding device. The relation betweenthe forces of the two springs is so regulated that the speed of thecarriage during its runs will be reduced to such an extent that when itis arrested by the impact of the cooperating tabulating stops 43 and 47,said impact will be much less than it would be if my invention were notemployed and the harmful efiects of a too severe impact will beconsequently avoided.

From an inspection of Fig. 4 't will furthermore be apparent that whenthe retarding devices are in operative position the toggle will bepractically straightened and the weight of the support 59 and the partscarried thereby will be supported by the pivot screw 79 and the pressuredue to said weight will not be transmitted to the actuated tabulator key50 to add to the touch of the latter, or the power necessary to maintainit depressed.

I'Vhen the actuated tabulator key is released the parts of thetabulating mechanismare restored to normal position in the usual manner.The light coiled spring 100 serves through its connections with the link80 to draw the latter inward or toward the left in Fig. 4, the force ofsaid spring being sufficient to break the toggle joint. As soon as thetoggle joint is broken, the support 59 and the parts thereon will berestored to normal position through the gravity of said support 59, andthe associate parts acting'through the connections on the release bail(comprising the side arms 97 and the cross bar 99) will restore thelatter to normal position as shown in Fig. 1.

Various changes may be made without departing from the spirit of myinvention.
